If the boycott was actually about artist payouts it would have happened a lot sooner. The real reason for the boycott is Daniel Ek being on the board of Helsing, a company developing AI military strike drones (AI murder drones, to put it emotionally). This is the man that become a billionaire off the backs of hard-working musicians and used that money to invest in a company furthering the militarization of AI. Morally unconscionable for a lot of people.
